Universal Multimedia Optic Disc Player and Its Application for Revocable Copy Protection

1. A program embodied on a computer readable medium for use in a media content player, said program comprising: computer-executable program code operable to cause the media content player to: load an auto-run playback program from a machine-readable vehicle into the media content player in response to the machine-readable vehicle being supplied to the media content player; use said loaded auto-run playback program to access content from the machine-readable vehicle and supply the content to a media presentation device coupled to said media content player; and read copy protection data included in the content by the auto-run playback program to effect copy protection , wherein the copy protection is effected by altering a media playback procedure by the auto-run playback program.

2. The program of claim 1 wherein said machine-readable vehicle is an optical disc.

3. A device for use in a media content player, said device comprising: a processor operable to cause the media content player to: load an auto-run playback program from a machine-readable vehicle into the media content player in response to the machine-readable vehicle being supplied to the media content player; use the loaded auto-run playback program to access content from the machine-readable vehicle and supply the content to a media presentation device coupled to the media content player; and read copy protection data included in the content by the auto-run playback program to effect copy protection, wherein the copy protection is effected by altering a media playback procedure by the auto-run playback program.

4. The device of claim 3 wherein: said machine-readable vehicle is an optical disc.

5. A universal optical disc player comprising: a disc drive with associated drive controller; a processor coupled to said drive controller; signal processing circuitry coupled to said processor and having an output port for coupling to a media presentation device; and a memory coupled to said processor and having a data structure defined there; the data structure comprising a virtual machine for hosting an auto-run playback program obtained from an optical disc placed in said disc drive; the auto-run playback program being operable to provide control instructions to said processor to cause said processor to access content from the optical disc and supply the content to said signal processing circuitry for output to the media presentation device; and the content including copy protection data and the auto-run playback program being operable to read the copy protection data to effect copy protection, wherein the auto-run playback program effects the copy protection by altering a media playback procedure.

6. A method of distributing content, said method comprising: placing an auto-run playback program on a machine-readable vehicle that contains the content including copy protection data; supplying the machine-readable vehicle to a playback system; loading the auto-run playback program into the playback system in response to said supplying; using the loaded auto-run playback program to access and supply the content to a media presentation device coupled to the playback system; and reading copy protection data included in the content by the auto-run playback program to effect copy protection wherein the copy protection is effected by altering a media playback procedure by the auto-run playback program.

7. The method of claim 6 wherein the machine-readable vehicle is an optical disc.

8. A playback system for playing back content, said system comprising: a machine readable vehicle containing an auto-run playback program and the content; a drive associated with drive controller; a processor coupled to said drive controller; signal processing circuitry coupled to said processor and having an output port for coupling to a media presentation device; and a memory coupled to said processor and having a data structure defined therein: the data structure comprising a virtual machine for hosting an auto-run playback program obtained from said machine-readable vehicle placed in said drive; the auto-run playback program being operable to provide control instructions to said processor to cause said processor to access content from said machine-readable vehicle and supply the content to said signal processing circuitry for output to the media presentation device; and the content including copy protection data and the auto-run playback program being operable to read the copy protection data to effect copy protection, wherein the auto-run playback program effects the copy protection by altering a media playback procedure.

9. The system of claim 8 wherein: said machine-readable vehicle is an optical disc.

10. A program embodied on a computer readable medium for use in a media content player, said program comprising: computer-executable program code operable to cause the media content player to: load an auto-run playback program from a machine-readable vehicle into the media content player in response to the machine-readable vehicle being supplied to the media content player; and read copy protection data included in the content by the auto-run playback program to effect copy protection, wherein the copy protection is effected by altering a media playback procedure by the auto-run playback program.

11. The program of claim 10 wherein: the machine-readable vehicle is an optical disc.

12. A device for use in a media content player, said device comprising: a processor operable to cause the media content player to: load an auto-run playback program from a machine-readable vehicle into the media content player in response to the machine-readable vehicle being supplied to the media content player; use the loaded auto-run playback program to access content from the machine-readable vehicle and supply the content to a media presentation device coupled to the media content player; and read copy protection data included in the content by the auto-run playback program to effect copy protection, wherein the copy protection is effected by altering a media playback procedure by the auto-run playback program.

13. The device of claim 12 wherein: the machine-readable vehicle is an optical disc.
